在考虑了沉淀指示剂的影响下，推导出了以林邦误差公式形式表示的沉淀滴定终点误差的计算公式。
The endpoint error formula which takes the form of Ringbom's error formula and involves the effect of the precipitation indicator in the precipitation titration has been derived.
该方法不用指示剂， 沉淀不必分离，具有终点直观、操作简单、快速准确、重现性好等特点。
The procedure doesn't use indicator and the precipitate doesn't to separate. The end point of titration is obvious. The operation is simple , fast , accuracy and good repetition.
